+  Introduce common attributes for consumer group and subscription name instead of per-system ones:
+  - `messaging.consumer.group.name` instead of `messaging.kafka.consumer.group`, `messaging.rocketmq.client_group`, and `messaging.eventhubs.consumer.group`.
+  - `messaging.destination.subscription.name` instead of `messaging.servicebus.destination.subscription_name`. Use it in the Google Pub/Sub conventions.
